Application filed September 23, 1914. Serial No. 863,864.

To aZZ whom it may concern Be it known that 1, CHARLES J. NASH, a citizen of the UnitedStates, and resident of Chicago, county of Cook, and State of lllinois, have invented certain new and useful Improvements in Draft-Rigging, of which the following is a specification, and which are illustrated in the accompanying draw,- ings, forming a part thereof.

The invention relates to draft rigging for cars, and particularly adapted for use on comparatively light cars such as are in sci-v ice in subways and on interurban lines.

The objects of the invention are to provide a simple construction, and improved means for securing pivotal relation between the coupler and the gear.

- The features of the invention are hereinafter pointed out in connection with its description, and an embodiment of it is illustrated the accompanying drawings, in which- Figure l is a detail longitudinal "ertical section of a car taken on the center line of draft; 2 is a detail plan view, partly in section, 0 the draft rigging; Fig. 3 is a view in perspective of the yoke or coupler extension; Fig. f is a transverse sectional view on the line -l-t of Fig. 2; Fig. 5 is a view in perspective-of the follower; and Fig. 6 is a view in perspective of one of the draft plates.

y is provided-with a The center sills of the car are represented at 10, 11, and are shown.- as being united by a cover plate 12 and as carrying a-boxlilzc draft sill 13, the side walls of which are riveted to the center sills, its bottom is foriningthe means of attachment of the draft ri ging. These features are not-novel.

The-craft plateslfi, 16, are alike except that they are made as rights and lefts. Each vertical. wall having at its upper edge aiiange 17 which extends outwardly and inwardly and bears against and is riveted to the-bottom 14; of the draft sill. At its inner end the draft plate is provided with an instanding shoulder 18, which as tends to the center-line .of draft and at its inner edge has a vertical rearwardly-entend ing flange 19. The flange 1'? extends hackwardly to the rear end of the flange 19, with which flange it is integrally The two draft plates are secured together by means rivets 20 set through their flanges lit and also by means of a bottom tiaplate preferred form.

21 riveted to outstanding bottom flanges 22. The draft plates are provided with such external ribs and fillets as maygloo deemed essential to strength. At the forward'ehd each draft plate is provided with instandi'n'g draft lugs 23, 24, for engagement by a forward follower; these lugs being vertically alined and spaced apart to accommodate the yoke or coupler extension, as hereinafter described.

The butt 25 of the coupler is horizontally slotted from its inner end to receive the yoke, and is rounded to permit it toturn freely upon the follower. The yoke or'coupler extension, designated as a whole by the numeral 26, is shown as in the form; of a-- continuous loop having parallel sid Inem bers 27, 28, anda-tfiat'grearend 29 which is I (amended upwardly and downs preferably I wardly to 'inc'rease the bearing surface for the cushioning element and the bufiing' shoulders. The forward end 30 of the yoke.v

is rounded and adapted to fit within theslot of the coupleu'hutt, and isslotted, as shown at 81, to receive a pivot pin 32 for uniting it with the coupler.

Each of the draft vided with an instanding longitudinal ledge 33, upon which, and the the sidcmembers 27, 28, tension rest and slide. To facilitateassembling'the forward end of the ledge terminates some distance fromyfshc draft lug 2%, the upper face ofwhich is in effect a con tinuation of the ledge." A single follower is employed, and takes the form of a plate 3% having near its upper and loweredges laterally projecting wings 35, 36; the upper wings resting and sliding upon the side members 2'2", 28, of the coupler extension. Tie forward facev of the follower is provided with a boss 37, having a concave face to receive and form a bearing for the end of the coupler butt. The curvature of the end of the coupler eX-.

of the coupler butt is'concentric with the" it pivot pin 32.

The cushioning mechanism may be. of any There is shown in the rawings at 38 a common type of Westinghouse friction draft gear, and the other elements of the device are shown as especially designed for its accommodation. end of the cushionin mechanism bears against the rear end 0 the coupler extension, and its forward end against the follower draft lugs 24 l The rear rue lower plate 34:. In draft the cushioning mechanism is compressed by he forward movement or the coupler extension, the

stress being transmitted to the car through the lugs 23, 24. In bu'if the follower p late Y 34: is pushed inwardly by the coupler, compressing the cushioning mechanism, the

stresses being transmitted through the rear end of the coupler extension anl the shoulders 18.

The coupler is free tooscillate about the pin 32, its end turning in the concave face of the boss of the follower, and the" pin 32 travels baclnvardly in the slot 31 of the yoke in buffing.

1 do not desire to be hunted to the particular design or details of the device as illustrated in the drawings, the invention being of the scope defined in the following ous loop for inclo'sing shock-absorbing elefor inclosing shock-absorbing elements the forward end of the loop entering the slot of the coupler and being provided with a longitudinal slot through which the pin passes.

3. In a draft rigging, in combination, a coupler having its rear end horizontally slotted, a pin set vertically through the coupler and crossing the slot therein, a coupler extension in the form of a continuous loop for inclosing shock-absorbing elements, the forward end of the loop entering the slot of the coupler and having a longitudinal slot opening through its inner face and within which the pin is located.
